Abstract

The purpose of this study was to select packaging films and active modified atmosphere packaging (MAP) to maintain fruit quality and extend the shelf life of strawberry cultivars for export purposes. The best results for firmness, soluble solids content (SSC), titratable acidity (TA), and decay percentage were obtained from 30 µm (2,500 cc/m2·day·atm O2 permeability) of oriented polypropylene (OPP) film, which was found to be suitable as MA packaging material for strawberries. After eight days of storage with active MAP with 5% and 10% CO2, significant differences were observed between the tested cultivars. The firmness of “Kumsil” remained high in the range of 4.0–4.4 N, while “Kingsberry” was maintained around 2.8 N. The SSC was lower in the treatment groups than in the control, and lower in “Kingsberry” than in “Kumsil”. The TA also showed trends similar to those of SSC and was maintained at approximately 6.3 mg kg-1 in both the “Kumsil” and “Kingsberry” cultivars. The decay percentage of “Kumsil” was lower in the treatment groups (around 1.1%) than in the control (1.5%), and the lowest (0.8%) was observed in “Kingsberry”, with an active MAP at 10% CO2. The overall sensory evaluation of sweetness, sourness, texture, freshness, and aroma showed the highest score in MAP in the 5% and 10% CO2 treatment groups on the eighth day of storage. Therefore, the results demonstrate that “Kumsil” and “Kingsberry” could be marketable for six and four days, respectively, based on fruit marketability.
